If you have more time than money, you should consider building your own solar photovoltaic (PV) panels – from scratch! With just a few hours of instruction and supplies you can purchase on eBay and your local home improvement store, you can construct your own solar PV panels.
You can make your own solar PV panels for about $1.00 a watt. You’ll be so proud of yourself when your homemade panel starts putting out power. “Look everyone! I can light up a light bulb with power from the sun.” Then…(unless you have a bunch of free time) reality will hit you and you’ll get out on the internet, find out you can buy panels for about $1.50-$2.50 a watt now, and buy the rest of your panels online.
You know you want to make at least one to prove to yourself you can, so the books shown below contain all the knowledge you need. They also have lots of illustrations and explanations for this project.
